A Fast Algorithm to Simulate Droplet Motions in Oil/Water Two Phase Flow
Procedia Computer Science, 2017 Abstract To improve the research methods in petroleum industry, we develop a fast algorithm to simulate droplet motions in oil and water two phase flow, using phase field model to describe the phase distribution in the flow process. An efficient partial difference equation solver—Shift-Matrix method is applied here, to speed up the calculation coding
